Abstract:
A field experiment was conducted during Rabi 2019 to study the effect of humic acid (HA) at Organic Farming Research Institute, UAS, Raichur during 2019-20. Various methods of humic acid application (viz., seed priming, soil application and foliar spray) in combination and at different concentrations was used to study the effect of humic acid on crop performance, nutrient uptake and nutritional quality of rabi sorghum. The experiment was laid out in Randomized Complete Block Design with 10 treatments. Significantly higher grain yield of sorghum (1662 kg ha-1) and nutrient uptake was recorded in treatment T9 due to application of recommended dose of N through FYM along with seed priming in 1 percent HA solution, soil application of HA @ 10 kg ha-1 and foliar spray @ 0.5 percent compared to supplementation of N through FYM, seed priming in 1 percent HA solution and soil application of humic acid @ 10 kg ha-1 alone (T5: 1365 kg ha-1). The results revealed that significantly higher growth parameters were recorded in treatment receiving FYM along with seed priming, soil and foliar application of HA. The net return realized from T9 and T10 (Seed priming with cow urine @ 25 percent + RDF + FYM) treatment was ` 23612 and ` 22576, respectively.
